hicle-wheels having a center or web portion ;and-a* fel ly portion connected by mterme diate-sprmgs or cushions so arranged as to both'suspeno'i and sup ort the center. portion centrally within the fe y ortion, so that the shocks sustained by the ielly o1 tread of the;

Wheel will be cushioned before transmission to the hub, and consequently a cushioned, easy running, and *durable wheel will be pro- -v1ded;sav1ng wear on the'vehicle running-gear and on the wheel-tires and enabling pneumatic tires tobe dispensed with. i I

The present invention relates principally to the wheel asan entity and embodies various novel features of construction and 'con'1- binationsof parts hereinafter described and claimed. Subsidiary features of the wheel,

which may beapphcabl'e to different kinds undue rotative movement of the felly an I center'relatively to each other and also imdue wear on the rim of the center. Another feature is" a novel means for cushion-tires cree ing on the fe y. These andother novel details of construction will be clearly understood from the accompanying drawings and. the following description, and the'parts for which protection is desired herein are set forth in the claims.

a means for preventing too great rotatorial lay of the wheel-center relatively to the elly, beingadapted to engage notched plates said plates being preferably sunk into the. surface of rim a and having outwardly-pro- .jectin lugs g, which lie on 0 posite sides of the a jacent bolt E and wil engage therewith and prevent undue rotatorial moveto the other in starting or sto pin the whee thus relieving the springs o suc 1 duty and the wheel which would arise if the springs were subjected to severe lateral distortion. The plates G may be secured in place by screws g, and they also serve as hearing or Wear plates to prevent the side plates E cutting into the wood rim 0 The corrugated band F prevents the cushion-tire creeping on the felly, which is such an objectionable and dangerous feature of such tires, and thus insures better tractive action of the wheel. 7

Obviously the invention could be a plied notonly to ordinary road-vehicle whee s, but also to tram-car and other wheels. Thus, as indicated in Fig. 4, the cushion-tire F is replaced by a flanged metal tire H, so that a the resultant wheel is adapted to be used on a rail. When adapted to car-wheels, as shown in Fig. 5, the wheel-center,comprising the hub K, spokes 7c, and rim is, could be made in one casting or part, if desired, and the felly could be made integral with the tire; As shown in Fig. 6, two sets of springs D are em loyed. Such construction would be espe cia ly useful for wheels which have to carry very heavy loads. 3

It will be noted that by this construction of wheel the centers are not only sup orted the uppermost springs, the springs at'diametrically o posite points reinforcing and assisting eac other; also, that the rotatorial play; of the wheel-center and felly relative-to eac other is limited; but sullicient pla is allowedthe center both rotatorially an radially to ipsure thorough cushioning action. Excessive loading on the axle would ma crush the sprin s, butwould cause the rim a to settle onto t 1e stay-bolts E. If by accident any sprin or springs should be broken, the wheel coul still be used 'until the vehicle Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
